Closed-Cell Spray Foam Insulation Services in Fort Worth, Arlington & Surrounding Areas

Attic Zone Insulation installs closed-cell spray foam insulation for homeowners throughout Fort Worth, Colleyville, Arlington, Southlake, Keller, and Hurst. We specialize exclusively in closed-cell foam because it delivers a higher R-value per inch and doubles as a moisture barrier — a combination that holds up better to North Texas heat and humidity than open-cell foam or traditional insulation. Spray foam is applied as a liquid that expands into a solid, air-sealing layer — filling gaps, cracks, and hard-to-reach spaces that batt or blown-in insulation can't reach.

We offer free, no-obligation estimates for spray foam projects across our service area. Call 817-500-1943 to schedule yours.

​

What Is Spray Foam Insulation?

​

Spray foam insulation is made from two liquid components — typically polyurethane or polyisocyanurate combined with a blowing agent — that mix at the spray nozzle and expand on contact. Within seconds, the mixture hardens into a solid foam that adheres to surfaces and seals gaps that air, moisture, and pests would otherwise pass through. It's commonly installed in attics, crawl spaces, walls, and roof decks, and it's especially effective in irregular or hard-to-reach areas where rigid insulation doesn't fit well.

​

Why Attic Zone Insulation Uses Closed-Cell Spray Foam

​

Not all spray foam is the same. Closed-cell spray foam is denser and stronger than open-cell foam, with a higher R-value — typically R-6 to R-7 per inch, compared to roughly R-3.5 to R-3.6 per inch for open-cell. That extra density also makes closed-cell foam a moisture barrier, helping protect against water intrusion, mold, and wood rot in crawl spaces, rim joists, and exterior applications.

Attic Zone Insulation installs closed-cell spray foam exclusively. It costs more per square foot than open-cell, but for Tarrant County's humidity and heat, we believe the added moisture resistance, structural rigidity, and long-term performance make it the better investment for our customers.

Benefits of Closed-Cell Spray Foam for North Texas Homes

​

Superior R-value. Closed-cell foam delivers more insulating power per inch than fiberglass, cellulose, or open-cell foam, which matters when attic space or wall cavities are limited.

Air sealing. Foam creates a continuous, airtight barrier that stops the drafts and air leaks that drive up cooling costs during Texas summers and heating costs in winter.

Moisture resistance. Closed-cell foam acts as a moisture barrier, helping protect against mold, mildew, and wood rot — a real concern in Tarrant County's humid months.

Added structural strength. Closed-cell foam's density adds rigidity to the surfaces it's applied to, which open-cell foam doesn't provide.

Pest deterrence. Unlike loose-fill insulation, foam doesn't leave the open channels that rodents and insects use to nest.

Long-term durability. Closed-cell foam doesn't sag, settle, or compress over time the way batt insulation can, so its performance doesn't degrade over the life of your home.
